Police made an arrest in the slaying of 32-year-old Lisa McQuirt very quickly, something they announced the same morning as the shooting.

It turns out the 911 calls gave them a heads up on their suspect.

About 4:45 a.m. Monday, Clark County's 911 lines lit up.

"I live in a duplex and I just woke up to hearing gunshots," a caller told 911 dispatchers.

Witnesses helped detectives track down the suspect in McQuirt's death.

"There was a man just on Kenwood Avenue that was in a pickup truck and he let the air out of some tires out of here and now he shot a gun," a caller told 911 operators.

Police said the man callers described was 44-year-old Ronald Shewmaker.

They said the two used to date, but they were still trying to figure out the extent of their relationship and why she was shot at point-blank range.

Before police arrived at the scene, callers alerted them to details about the suspect.

McQuirt's family said she met Shewmaker at her job, and that she considered getting a restraining order against him just before her death.

Police arrested Shewmaker at his home in Corydon shortly after the shooting.

Shewmaker has been preliminarily charged with murder, but hasn't appeared in court yet because after being booked into Clark County Jail, medical staff there said he showed odd behavior and appeared to be in distress.

He was sent to Clark Memorial Hospital, which at last check was still holding him.
